ASSIGNOR TO rlHE DRY DOCK,

STREET-CAR LAIVlP.

SPECIFICATION forming part of Letters Patent No. 365,062, dated June 21, 1887.

Application filed January H, 1587. Serial No. 224,317. (No model) T 0 @ZZ whom t may concern:

Be it known that I, Crimen E. GREY, a citizen of the United States, residing at New York, county of New York, and State of New York, have invented certain new and useful Improvements in Street-Cars, i'ully described and represented in the following specification and the accompanying drawings, forming a part of the same.

rlhis invention relates to the construction of ordinary street-railway ears, and particularly to certain features in the construction of such cars, the purpose of which is to secure better lighting for the ears.

The lighting of street-cars was formerly almost always effected bynieans of one or more lamps or candles placed at the end or ends of the car, but of late, and particularly in the better classes of cars, it has been found most desirable to provide, in addition to the end lights, one or more lamps, which is or are lo` cated overhead and beneath the raised central portion of the roof.

In the constructions heretofore in use the lamp or lamps located overhead have been so constructed and arranged that it was necesv sary to provide the roof of the car above the lamp with an opening, in order to secure proper draft for the lamp, and the results attained by these constructions have not been entirely satisfactory, owing to the fact that the stopping and starting and the otherwise unsteady motion of the car created an irregu` lar draft through the lamp-chimney and the opening above it, which caused the lamp to flicker and smoke. A further difficulty was found to exist in the fact that with the constructions heretofore in usc it was impossible tosecurcan even diffusion of the light throughout all portions of the ear, some parts being very much better lighted than others.

lt is the object of the present invention to overcome these objectionable features and to provide a construction which will` secure a steady unflickering light which will be evenly diffused throughout the car.

Asa full understanding of the invention can be best given by an illustration and description of the parts of a car embodying the same, all preliminary description of the invention windows, d.

will be omitted and a full description given, reference beinghad to the accompanying drawings, in which- Figure 1 is a crosssection of the upper or roof portion of astrect-car constructed aecording to the present invention. Fig. 2 is a plan view of the central portion of Fig. 1, looking upward, and Fig. 3 is a sectional View similar to Fig. l, but taken at right angles thereto,or lengthwise of the ear.

Referring to said figures, it is to be understood that A represents the sides, and B the roof, of an ordinary Streetcar. The roof B is provided over the center of the car with the usual raised portion, C, the sides c of which are provided with the usual small Ventilatingrlhe top e of this raised portion C is provided about midway of the length of the earwitha low dome or closed elevation,

D, having a flat or substantially flat closed or 7o solid top,f, and inclined sides g, which slope outward to the portion e.

The lamp h is so constructed as to burn freely without ventilation through the root, and is suspended beneath the center of the' 75 dome D and close to the roof j' by means of rods t', which depend from the top of the dome. rlhc dome D is of the square or rectangular form shown, as this form will secure the best results. rlhe sides `g of the dome are lined So or covered upon the inside with reflectors Z, which consist of sheets of polished metal.. rlhe top j' of the dome will preferably also be provided upon its under side with a plate, m, which will act to reflect the-light downward.

In addition to the parts already described, the rods fi may also support a reflector, a, of the ordinary form shown.

By means of the construction which has been described the lamp h is raised sufficiently to 9o be out of the way of the heads of passengers walking or standing in the central aisle of thc car without being so surrounded by the parts ol' the roof of the car as to prevent its light from radiating horizontally in all directions, and at the same time the large extent and slight inclination of the reflect-ors Z, which is made possible by the shape and arrangement of the dome D, causes the light, instead of being rcn flected directly or nearly directly downward, Ico

to be diused throughout the wholeor nearly whole extent of the car, thus giving uniform or substantially uniform light to all parts of the car, and at the same time, the roof of the dome D being solid, the stopping and starting and other irregular movements of thel car cannotproduce irregular drafts through the lampchimney, so as to cause the flame to flicker and smoke.

I am aware of the construction described in United States Letters Patent No. 161,566, and I do not claim the construction therein shown and described; but,

Having thus described my invention, what I do claim as new,and desire to secure by Let ters Patent, is-

In a Streetcar, the con'ibination, with the roof B, having the raised portion C, of the square or rectangular closed elevation D, rising above the top of the portion C, and having a closed flat, or substantially flat, top, f, and inclined sides g, provided with reflectors Z, and the lamp 71, suspended beneath and from the top of the dome, whereby thclamp wlll notbe subjected to unsteady draft and will have its light evenly diffused throughout the car, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses. l
